Portable electronic device display assemblies and methods and apparatus for manufacturing the same
A display includes an upper surface adapted to present visual information to a device user and an outer perimeter proximate the upper surface. An optically transparent lens is carried by a housing and overlies the display. The optically transparent lens and the upper portion of the housing together define an upper surface of the portable electronic device. An optically transparent resin is carried between the display and the optically transparent lens. The optically transparent resin includes a perimeter portion disposed between the outer perimeter of the display and the side portion of the housing. The resin can be cured using light.
LAMINATED MIRROR LENS
A lens for eyewear is configured to reduce the appearance of scratches on the lens and/or increase the durability of the lens. The lens can include a functional stack bonded to a lens body. The functional stack can include a functional layer, such as a thin film coating, sandwiched between the lens body and an optical-grade transparent film. The functional stack can increase abrasion resistance and environmental durability of the lens, and can reduce the appearance of scratches on the lens. The combined lens body and functional stack can increase the durability of the lens relative to a lens with a thin film coating (e.g., a gradient or mirror stack) on an external surface of the lens.
